Feb 03, 2017 · The use of the copper crusher for pressure measurement is rapidly giving way to the quartz crystal piezoelectric pressuremeasurement system, which is less timeconsuming and more precise than the coppercrusher system.
These terms were adopted by convention to indie that the pressure values were measured by copper crusher and lead crusher ...chamber pressure was the copper crusher method. Up until that time, what we now call CUP was commonly known by two different names: CUP and PSI. The two were used practically interchangeably.
Use the copper crusher numbers with the Powley Computer. ... Crushers are copper or lead cylinders deformed by the piston. The deformed length of the crusher is measured and compared to a table supplied by their maker with each lot of crushers. The pressure is read directly from this table.
Records of pressures were obtained by using the same copper crusher cylinders for several rounds. These were compared with the pressures obtained by the usual method during the firing of pressure rounds in the 105 mm, 12 inch and 14 inch guns.

Gun chamber pressure is an important parameter in proofing of ammunition to ensure safety and reliability. It can be measured using copper crushers or piezoelectric sensor. Pressure calculations in copper crusher method are based on linear plastic deformation of copper after firing. However, crusher pressure deformation at high pressures deviates from the corresponding values measured by ...
